<p>A method for heating glass batch materials before use in a glass melting furnace, the glass batch material comprising solid particle raw materials or cullet, or a mixture of the two, the method comprising the steps of: a) providing a bulk quantity of glass batch material in a hopper; b) providing at least one gas flow tunnel through the bulk quantity of batch material, at least a portion of the surface of the tunnel consisting of a surface of the batch material; c) passing glass furnace exhaust gases through the tunnel; d) providing an electrically conductive electrode within the tunnel; e) providing an electrically conductive surface in contact with the batch material; and f) applying an electrical potential difference between the electrode of step d) and the surface of step e) of sufficient magnitude to produce corona discharge inside the tunnel, the corona discharge consisting of a flow of gaseous ions through the furnace gases, at least a portion of the gaseous ions flowing into the glass batch material. <IMAGE></p> |
